网格环境下CAD模型的建立与共享

在研究三维模型检索技术的基础上,将网格技术及P2P技术融合在三维模型检索中,提出了一种新的建立与共享机制,给出了相应的设计模型,实现了CAD模型库的异构数据资源整合.对OGSA-DAI实现CAD模型的建立、特征提取、相似性匹配以及P2P技术实现CAD模型共享做了详细的阐述.该设计模型比传统的C/S模式或B/S模式更具有开放性与实用性,提高了CAD模型设计的效率.

Establishment and sharing of CAD model in grid environment

Grid and P2P technology is merged into 3D model searching based on 3D model searching technology,a new establishing and sharing mechanism is introduced,the corresponding design model is given,the isomerism data resource integration of CAD model library is realized,OGSA-DAI realizing CAD model establishing,feature extraction,similarity matching and P2P technology realizing CAD model sharing are expounded in detail.This model has more openness and practicability than the traditional C/S and B/S scheme.The eff...
